Thermalright XP90C vs. Cooler Master Hyper 48
Any thoughts will be appreciated in regards to cooling a P4 3.0 Socket 478.
Something to bear in mind with both of those heatsinks is that they are very heavy (XP90C ~700g, Hyper 48 >800g). I have the Hyper 48 and I wouldn't recommend it to anyone. There is really no cooling advantage from having an all-copper heatsink, because of the added risk of the weight of the coolers. Aluminium will do the job just as well and with no risk of warping your motherboard.

I was interested in their methods of mounting this particular fan to the 7000.
I had nightmares about the fan falling off of the heatsink while it was running so I couldn't bring myself to tape or tie it into place. I drilled the hole pattern in the stubs so I could use some small sheetmetal screws to attach it to the Zalman mouning bracket. I then stuck some silicon washers onto the fan hub to decouple the fan from the metal bracket once I assembled it:
I fastened the fan to the bracket useing some more silicon washers to decouple the screws fron the metal bracket:

Another way is to use zip ties, like I did.

I compared the XP-90 to the Hyper48 and they were very evenly matched, the XP-90C is a bit better than the XP-90, so the conclusion would not be very hard to make;)

I am currently using the XP-90 to cool an overclocked AMD64-3000. For my system, I did precisely what mckennaiii has suggested and used a Zalman Fan Bracket to suspend a fan over the heat sink.
In my system, this solution has worked fine. Prior to installing the Zalman fan bracket, I put the fan bracket in a vice and slightly bent the fan bracket so that the fan is suspended around 1/16" above the heatsink. This solution has a couple advantages:
* The low clearance between the fan and the heatsink doesn't provide airflow with much ability to do anything besides passing through the fins on the heatsink.
* Hanging the fan at the end of the fan bracket reduces the overall weight of the heatsink.
While you might get lower temperatures with direct mounting, my guess from looking at my heatsink is that it wouldn't make much difference. If you try it both ways, please post your results to the list.

I did some research before buying the Hyper 48 and it seemed to be similar to the XP-90.
I only went for the Hyper 48 because it already had a good fan and socket 775 mounting system.
About the weight, I really don’t know why people worry so much. I have moved recently and I’m always carrying the computer around the house to make some kind of changes and my motherboard is still intact. And I must say I am not the most careful person in the world.

Sooo mckennaiii, I have to say that you were right to get the XP-90C. I just tried the SI-120 and the results are amazing (to me at least)!
Room temperature was 23c, 2xCPUBurn for 30 minutes, tested at 12 Volts for reference using Speedfan. Noise was also approximately the same, to me.
Zalman 7000AlCu + Nexus 92mm @ 12V. 1400rpm: Idle 33c - Load 60c
SI-120 + Nexus 120mm @ 12V. 1000rpm pulling air: Idle 33c - Load 51c
SI-120 + Nexus 120mm @ 12V. 1000rpm pushing air: Idle 31c - Load 49
VRMs were below 60c with either cooler pushing, below 70c pulling.
And the AS5 hasn't even cured yet. I thought I'd see a 2-3c degree difference at load.
